Hello,

I've tried to program both 24LC eeprom and AT45 spi flash ram with no success on my eMega.
After that, I tried to measure voltage on both VCC pins of 24LC and flash ram.
Surprising, I've got 0V for both ? While I should read 3.3V  :'(
Be sure the eMega was powered before taking measure  ;)
Looking at C66, it's the same problem, 0 volt.
It's also the same thing for A2 of 24LC...

Is someone as the same problem ?
Is it a normal situation ?
Do I have to setup a switch ?

Merry Christmas,

Yoyo.
